The main variable being passed is #whoplayer#.
I need to be able to separate them into individual variables but I can't figure it out. Sometimes the variable passed is not separated by commas (only 1 items passed) (1245) other times it's multiple: (1245,1246,1250)
Check out cflib.org, there are a couple of tags there for handling csv data. Was not clear whether you meant actual CSV formatted data, or just data elements separated by commas. If the latter, then Dan's CFLOOP colution also works. If the former, then there are a few more variations that CFLOOP won't handle so easily, but those ahve been solved by the cflib.org tags.
